Typical Applications
This section provides some examples of typical test configurations
that demonstrate how an Agilent 8159xA/S Optical Switch module can
be used to achieve test automation, and improve test repeatability.
If your test configuration requires more than one 1x2 Optical Switch,
you can use the Agilent 81592A/S dual 1x2 Optical Switch modules to
reduce the number of mainframe slots required.
Selecting a Laser Source
In Figure 130, an Agilent 81591A/S 1x2 Optical Switch is used to select
one of two different sources (different wavelengths) as the input to the
DUT.

Selecting Measurement and Calibration
Paths
In Figure 131, an Agilent 81591A/S 1x2 Optical Switch is used to select
between the measurement path and the calibration path.
